Looking at the complex type definition for the ur-type[0] we note that its {content type} has a particle whose {term} is a sequence whose {particles} contains a single {term} which is wildcard with namespace constraint set to any.
In short, the content of a complex type of type xs:anyType is anything from any namespace. However, the default value of processContents[1] for a wildcard is strict meaning that a schema must be provided for each of the elements [or attributes] that appear in the content model.
So you can either provide a schema for all the extra elements and attributes appearing as part of the <first> element or create a type whose wildcard has processContents set to skip or lax and use that type instead of xs:anyType.

Subject: [xml-dev] Schema Sanity Check
Do the following Schema and instance look ok?
I keep getting an error saying the "<b>" elements are not declared, but
the type if first is anyType so should this not be anything I want??
Tried using MSXML 4.0 and .Net Schema classes.
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
<xsd:element name="name">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="first"
type="xsd:anyType" />
<xsd:element name="middle"
type="xsd:string" />
<xsd:element name="last"
type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
<?xml version="1.0"?>
<name xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="schema.xsd">
<first><b>Steven</b></first>
<middle />
<last>Livingstone-Perez</last>
</name>
Thanks,
Steven
